Perhaps there are many possible factors such as:
1. GROWTH HORMONES (GH) or somatotrophin and chicken prolactin/ovine prolactin administered by the poultry manufacturing industry in chickens, subsequently affects the pituitary gland to produce breast milk hormones (the fact that I've changed my diet from an Organic Raw Vegetarian to Semi Vegetarian which includes fish and poultry of non organic producers) which increase breast size in humans this would be chicken prolactin which increases the size of chickens and 'fattens' the chickens; (check out: http://www.freepatentsonline.com/5053391.html)
2. GLAND STIMULATION from SUCKING THE BREASTSduring love making. The blood flow stimulates the glands of the breasts.;
3. ENLARGED PITUITARY CONDITION -- The pituitary gland in addition to producing other hormones for glands like the adrenals (ACTH), growth hormones (GH), thryoid (TSH), follicles for hair (FSH), to name a few, also produces the prolactin hormone (PRL) for breast milk growth. An imbalance can cause a tumor in the Pituitary Gland called hyperprolactinaemia.
4. MEDICATIONS such as metoclopramide or thioridazine cause increased levels of the prolactin hormone;
5. DUCT ECTASIA in older women can increase milk secretion in the breasts.
